AUT'QMOBI'LE PUMP.

v `Application .filed July 6, 1926. Serial No. 1231572131 The presentinvention relates to an air pump inl the form of an attachment forjanautomobile and `has for its prime object to provide a structure which isexceedingly compactand convenient, one which is efficient and reliablein operation7 strong, durable and simple in construction, inexpensive tomanufacture, easyto manipulate, and otherwise well adapted to thepurpose for which itis designed-` 'lVith the above and numerous otherobjects yin view as will appear as the descrip-- tion proceeds, theinvention resides in certain novel yfeatures of construction, and in thecombination and arrangement of parts as will be hereinafter more fullydescribed and claimed.

In the drawing Figure 1 is an elevation of the device embodying thefeatures of our invention,v

Fig.2 is another elevation thereof taken at right angles to that shownin Fig. l.

Referring to the drawing in detail, it will be seen that 5 denotes aframe in the form of a plate having an apertured car A(i extending fromone'edge thereof intermediate its ends so that the said frame may bebolted as is indicated at 7 on an automobile engine.

The frame plate extends vertically and at i v 15 radiating therefrom towhich is pivotally engaged as at 16 in any suitable manner, theextremity of the piston r'od 12.

As the description has thus far progressed, it will be seen that as theworin gear 14 rotates, the piston rod 12 will be reciprocated as isdesirable for operating the pump and simultaneously with thercciprocation of the piston rod 12, the cylinder 10 and rod 12 willoscillate in respect to vthe pin 8. .This permits the very compactarrangement of the parts and allows them to' operate withgreatetiiciency. j

A shaft 17 is journaled in bearings 18 and 19, and has a worm portion 2Oformed thereon meshing with a Worm gear 14. An arm 21 is rotatable atone endl on the shaft 17,

against a l through the rodA 23.

holds the gear 27 in mesh therewith.

at one edge of the plate frame.` A gear 22 is fixed to the shaft 17,adjacent the arm 21.

A rod 23 is engaged with the arm 21 and pierces an opening provided in abracket projecting from one edge of the plate frame 5. A spring isdisposed about the rod 23 and impinges against the bracket 24: and j pin26 extending transversely A gear 27A is journaled on a` stub shaft 28 atthe free end of the arm 21, and is always in mesh with the gear 22. Indotted lines in Fig. 2, we have indicated adrive gear 29 which maybeoperated by any shaftl of the internal combustion engine, preferably the(jrank shaft, and the spring 25 normally A cam 30 is Ymounted on theupper end of the rod 23 and by swinging this cam` upwardly. the rod 3may be lifted as the cam bears against t'he bracket 24, thereby swinging'the arm 21 upwardly and n iovingT the gear 27 out of mesh with the gear29. 4 r

Normally the cam 3() will be in itsraised yposition so as to maintainthe gear 2T out of mesh with the gear 29, thereby normally holding *thepump inactive. In order to pump a tire up, the camz is swung down-Awardly thereby causing the spring 25 to act upon the rod 23 :forswinging the arm 21 dcmfnwardly so to mesh gear 27 with gear 29. Thus itwill be scen that the gear 29 drives gear 2i' which in turn drives gear22. The rotation of gears 22 sets uplrotary motion in the shaft 1T sothat the worm 20drives the worm gear 14 for causing the Operation of thepump as has heretofore beenr explained.

lt lthought that the present embodiment of the invention will be clearlyunderstood without a more detailed description thereof, and has beenshown merely by way of example, since in actual practice it attains thefeatures of advantage enumerated asdesirable in the statement of theabove invention and the above descrijiition. Apparently, numerouschanges in the details of construction, and in the combination andarrangement of parts, may be resorted to without invention ashereinafter claimed, or sacrifie? ing any yof-'its advantages.
